Compiler DesignConsider the context free grammar: S \rightarrow SS + | SS * | a; eliminate left factoring and left recursion from the grammar. Does these removals make the grammar suitable for top-down parsing? Justify.20227m Compiler DesignWhat is left recursion? Eliminate the left recursion from the following grammar : E \rightarrow E+T|T T \rightarrow T*F|F F \rightarrow (E)|id20197mCompiler DesignConsider a grammar A \to a S_1 | a S_2. The left factored grammar produced from the grammar is (i) A \to a A', A' \to S_1 | S_2 (ii) A' \to a A, A \to a S_1 | a S_2 (iii) A \to a A', A' \to S_1 | S_2, S_1 \to S_1, S_2 (iv) None of these20232m Compiler DesignChoose the correct answer of the following: To convert an arbitrary CFG to an LL(1) grammar (i) factor the grammar alone (ii) remove left recursion alone (iii) remove left recursion and factor the grammar (iv) None of the above20192m
